中文摘要:
      为了提高钨铜药型罩的侵彻性能和稳定性,在传统钨铜制备方法的基础上,采用机械合金化方法进行混粉,利用旋模压制方法进行压制药型罩毛坯,再在甲醇裂解气体的保护下进行烧结,最终制备出钨铜药型罩。利用排水法测试了烧结前后钨铜药型罩的密度。并将制备出的钨铜药型罩与紫铜板药型罩进行侵彻性能的实验比较。实验结果表明:钨铜药型罩烧结后的密度比烧结前的密度要低一些,但其对603均质装甲钢的侵彻性能要优于紫铜板药型罩的侵彻性能,与紫铜板药型罩相比,其穿深可以提高45%。
英文摘要:
      In order to improve the penetration performance and stability of tungsten-copper shaped charge liner, a new W-Cu shaped charge liner was prepared. Based on the traditional tungsten-copper preparation method, a series of new technology was adopted including using mechanical alloying method to mix powder, using spin-mode suppression method to press the blank of shaped charge liner then sintered under the protection of methanol cracking gas. Density of W-Cu shaped charge liner before and after sintering was tested by drainage method. The penetration performance was compared experimentally between the W-Cu shaped charge liner and the copper plate shaped charge liner. Results show that the density of W-Cu shaped charge liner after sintering is lower than the density before sintering; for 603 homogeneous armor steel plate, the penetration performance of W-Cu shaped charge liner is superior to copper shaped charge liner, and the penetration depth increases up to 45% compared with copper plate shaped charge liner.
